摘要：
中微子实验常使用大体积的水、有机闪烁体或惰性液体作为有源探测材料。由于涉及巨大的流体静压力和浮力，必须精确掌握探测器罐体内部的液位情况。本文介绍了TruSense S310激光测距系统的主要特性。该系统可在不与液体直接接触的情况下，透过防气丙烯酸窗口进行液位测量，从而满足目标液体严格的放射纯度和化学要求。我们报告了一系列实验室实验的结果，包括短期精度测试（±5 mm）和长期稳定性研究。此外，我们证明了该红外激光可在标准双碱光电倍增管（PMT）工作时使用。我们还讨论了该系统在OSIRIS预探测器中的机械布局与集成方案，OSIRIS预探测器将用于监测大体积中微子实验JUNO的液体闪烁体的放射纯度。
英文摘要：
Neutrino experiments often use large volumes of water, organic scintillators or noble liquids as active detection material. Due to the large hydrostatic and buoyancy forces involved, precise knowledge of the liquid levels inside the detector tank are mandatory. Here we present the main characteristics of the TruSense S310 Laser Range System. Level measurements can be performed without direct contact to the liquid and through a gas-proof acrylic window, thus preserving the strict radiopurity and chemical requirements of the target liquid. We report the results of a suit of laboratory experiments for short-term precision tests ($\pm$5\,mm) and long-term stability studies. Moreover, we demonstrate that the infrared laser can be used while standard bi-alkali PMTs are operational. We discuss the mechanical layout and integration of the system in the OSIRIS pre-detector that will monitor the radiopurity of the liquid scintillator for the large-volume neutrino experiment JUNO.
